Benefits of technology

The present invention provides a robot with two control units: the first control unit for overall operation and the second control unit to supplement the function of the first unit in case of malfunction. The second control unit has a low-capacity arithmetic unit to perform safety-considered motions that are simple and low-cost. This reduces the expense required to add the second control unit.

Problems solved by technology

When a software or hardware fault of the control unit occurs while the robot carries out a given instruction to perform a motion, the normal control of the robot may be impossible.
The robot, which is not controlled normally, may be abnormally operated and thus destruct other peripheral structures or persons.
Particularly, the safety-considered motion is limited to a relatively simple operation and a low-priced arithmetic unit having a relatively low arithmetic capability is employed as the second control unit performing the safety-considered motion, and thus expenses required to add the second control unit are cut down.

Abstract

A robot and a method for controlling the same are provided. The robot includes a first control unit to control the overall operation of the robot and a second control unit to supplement the function of the control unit in preparation for the malfunction of the first control unit such that the second control unit controls the robot to perform a predetermined safety-considered motion when the first control unit malfunctions.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application No. 2008-0087363, filed on Sep. 4, 2008, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Field[0003]Embodiments of the present invention relate to a robot and a method for controlling the same, and more particularly to a robot, which has one control unit to control the overall operation of the robot and another control unit to supplement the function of the control unit, and a method of controlling the robot.[0004]2. Description of the Related Art[0005]In general, robots are machines, which conduct motion similar to that of a human. Initial robots were industrial robots, such as manipulators or transfer robots for the purpose of automation and unmanned operation of production. Recently, a robot, modeled on the biped walking of a human, has been researched and developed. The biped walking has disadvant...
